In this issue of Photonics Focus, we celebrate the wide world of sports and how photonics technologies—now and on the near horizon—can assist athletes in efforts to up their game and stay safe on the field. One feature delves into the world of MoCap, or motion capture, a variety of imaging and analysis platforms that assist game officials with making calls on the field as well as allow athletes to analyze minute details of their performance. Another story takes readers inside the laboratories where researchers are pioneering new wearables technology to give athletes detailed information about how their bodies are responding to the stressors of competition.
